Orange Haze Blankets Indonesia’s Kalimantan, Threatening Health and Economy
A thick orange smog descended on Palangka Raya, forcing school closures and health advisories as wildfires in neighboring provinces released toxic ash. The haze has disrupted air traffic, increased healthcare costs, and prompted the government to allocate funds for reforestation and fire‑fighting efforts.

Thick orange smog descended upon Palangka Raya in Indonesia’s Kalimantan region, a stark reminder of the escalating wildfire crisis. The haze, generated by forest fires in neighboring provinces, obscured the city’s skyline and forced the closure of schools and hospitals. Residents reported respiratory distress, and local authorities issued health advisories urging the public to stay indoors.
The underlying cause lies in the cyclical practice of slash‑and‑burn agriculture, compounded by prolonged dry seasons and climate change. The government’s failure to enforce land‑use regulations has allowed illegal logging and peatland drainage to continue unabated, creating a tinderbox for fires. The haze has also disrupted air traffic, forcing the diversion of international flights and impacting the tourism sector.
The downstream impact has been a surge in healthcare costs and a decline in worker productivity due to illness. The Indonesian Ministry of Environment has announced a multi‑million‑rupee fund to support reforestation and fire‑fighting efforts. In the long term, the crisis may compel the country to adopt stricter environmental policies and invest in sustainable agricultural practices to mitigate future haze episodes.
